Case study of audio upgrade in private rooms of chain KTV
Release time：2025-09-28
AMRY Kaoraoke series have completed microphone system iterations in over 200 private rooms across 30 stores. To address issues such as high echo and blurry vocals in private rooms, they use heart-shaped directional wireless microphones combined with audio processing modules to balance the sound pressure levels of different performers through automatic gain control technology. With anti-interference frequency adjustment function, they completely solve the problem of signal crosstalk when multiple rooms are used simultaneously. After the upgrade, the number of consumer complaints decreased by 62%, and the store repurchase rate increased by 18%. Especially during peak hours, the microphone disconnection rate dropped from 8% to below 0.5%.
